Abstract
The invention relates to a translucent light-storing light-emitting polyvinyl chloride soft sheet which is characterized by comprising light-storing luminescent powder with the refractive index of 1.4-1.7, the grain diameter of 4-20micrometers and the weight percent of 1-8 percent, and the powder is coated by a polymeric layer with the thickness of 0.4-2 micrometers before compounding with polyvinyl chloride. The translucent light-storing light-emitting polyvinyl chloride soft sheet has better transparency than other luminescent plastic sheets, articles behind the sheet can be distinguished through the sheet in daytime, and the sheet can emit light at night so that people can distinguish the sheet and the articles behind the sheet. The translucent light-storing light-emitting polyvinyl chloride soft sheet can be used separately or used as an intermediate layer for fabricating household decorative products, such as tablecloth, dinner pads, table mats, and the like.
Description
Technical field
The present invention relates to a kind of plastics sheet, more particularly, the present invention relates to the luminous polyvinyl chloride soft sheet material of a kind of translucent light-accumulating, belong to daily plastic material field.
Background technology
Soft PVC (PVC) sheet material transparent attractive in appearance, quality is soft, has been widely used in daily goods field, as the tablecloth, mat applying and meal pad etc.This based article generally is that printed patterns is formed on the transparent PVC film, in the time of on covering furniture (especially glass furniture) face, both can show the pattern on the film, can see through the pattern that film is observed furniture again, has played the excellent decoration effect.But at the night or the weather of dim light, people just are difficult to perceive the existence of the transparent PVC film and the furniture that covers thereof, not only can not play decorative effect, can make collide with furniture and injured of people on the contrary.Adding luminescent powder in plastics can prepare at noctilucent plastics.Chinese patent CN200610047160.7 discloses a kind of light storage type self luminous plastic section bar, by substrate resin with contain the method production of the resin fusion co-extrusion of light storage type self luminous material, absorb visible light daytime after, in the dark can be automatic continuous luminous.Chinese patent CN200410086378.4 discloses a kind of long persistence luminous thermoplastic plastics composition and preparation method thereof, utilizing light-storing and emitting material and particle diameter is that the powdered rubber of 30～600nm prepares with the thermoplastic molten blend again, effectively improved the dispersion of luminescent material in thermoplastics, reduce the frictional force in the processing, improve the impact property and the luminescent properties of said composition, but be applicable to the product of making low-light (level) floodlighting when needing illumination effect and not having outer light source.But present luminescent plastics all needs to add the effect that a large amount of luminescent powders reaches luminouslighting, and is owing to the covering of luminescent powder does not observe the situation of its back, promptly opaque.
Summary of the invention
The objective of the invention is in order to solve above technical problem, provide a kind of translucent light-accumulating luminous polyvinyl chloride soft sheet material, this sheet material has the better transparency than other luminescent plastics sheet materials, in the daytime see through sheet material and can differentiate the article at its rear, night, the energy luminous made the existence of people's resolution itself and rear article.
The technical scheme that the present invention takes specifically provides a kind of PVC sheet material, contain polyvinyl chloride resin, softening agent, light-accumulating luminescent powder and other stabilization aids, the refractive index that it is characterized in that the light-accumulating luminescent powder 1.4～1.7, particle diameter, coats at 0.4～2 μ m polymer layer through thickness earlier before this powder and polyvinyl chloride are compound and handles 1～8% at 4～20 μ m, weight percent.Described PVC sheet material can mix plasticizing back calendering formation by heat, also can be made into earlier to stick with paste to be coated with behind the plastics to scrape moulding again.
The refractive index of employed in the present invention light-accumulating luminescent powder is limited to 1.4～1.7, because the refractive index of polyvinyl chloride resin can increase the transparency of slim PVC goods also in this scope.Refractive index mainly is the luminescent powder of silicates of rare earth of having mixed at the light-accumulating luminescent powder of above scope, as the Calucium Silicate powder of rare earth doped europium or dysprosium, merwinite, gehlenite etc., the Calucium Silicate powder of preferred rare earth doped europium.The particle diameter of light-accumulating luminescent powder is limited to 4～20 μ m, preferred 10～15 μ m.Because when particle diameter less than 4 μ m, the crystalline structure imperfection of luminescent powder, luminous efficiency is very low, when particle diameter greater than 20 μ m, reflection and the refraction action of luminescent powder in PVC strengthens, thereby reduces the transparency of PVC sheet.Similarly, the weight percent of light-accumulating luminescent powder is 1～8%, and preferred 3～6%.Because when weight percent less than 1%, light-accumulated luminous effect is reduced, when weight percent greater than 8%, reflection and the refraction action of luminescent powder in PVC is very strong, also can reduce the transparency of PVC sheet.The light-accumulating luminescent powder is before compound with PVC, need to handle with coating earlier with the PVC compatible polymers, used polymkeric substance can be an acrylic polymer, comprise polymethylmethacrylate, poly (glycidyl methacrylate), butyl polyacrylate etc., the preferred polymethylmethacrylate of the present invention.Method at light-accumulating luminescent powder surface coated polymer is a lot, comprises chemical graft polymerization, spray dried method etc., the preferred chemical graft polymerization of the present invention.A but example reference literature of chemical graft polymerization: high chemical journal, 2006,20 (5): 798-803.In addition, the thickness of polymer layer is limited to 0.4～2 μ m, preferred 0.7～1.2 μ m, because the thickness of working as polymer layer is greater than 0.4 μ m, can guarantee with the PVC blend before and after the blend, the spacing of inorganic light-accumulating luminescent powder is all greater than 0.8 μ m, and visible wavelength is at 390nm～780nm, just guarantee more to see through visible light, increase the transparency of PVC sheet.But the thickness of working as polymer layer is greater than 2 μ m, and forming such polymer layer difficulty at powder surface can increase greatly.
The luminous PVC soft sheet material of light-accumulating of the present invention can be cut into goods separately, also can be used as the middle layer of multilayer PVC sheet material, is used to prepare daily decorated articles such as the tablecloth, meal pad, mat applying, produces more decoration effect.Use the goods of the luminous PVC sheet material of light-accumulating of the present invention can see through visible light by day, keep the transparency of original PVC soft sheet material.After absorbing luminous energy daytime, goods can send soft light night, show the existence of goods and go up decorative pattern, see through the situation that goods can also be observed the furniture that goods cover simultaneously.
